	<h2>The ScrollView Widget With A Scroll Indicator</h2>

<p>In this example, we'll create a ScrollView instance, which also has a scrollbar indicator.</p>

<h3>Modules Used</h3>

<p>Since we want to use the base ScrollView, along with the ScrollViewScrollbars plugin, which provides the scrollbar indicator we use the <code>scrollview</code> module, instead of the <code>scrollview-base</code> module we used for the basic ScrollView example:</p>

<div id="syntax-7aa428b3b3a9681b4dac745bc5e5accf" class="yui-syntax-highlight"><div class="numbers"><pre class="javascript" style="font-family:monospace;"><ol><li class="li1"><div class="de1">&nbsp;</div></li><li class="li1"><div class="de1"><span class="co1">// Pulls in scrollview-base and scrollview-scrollbars plugin </span></div></li><li class="li1"><div class="de1"><span class="co1">// and plugs it in (at the class level)</span></div></li><li class="li1"><div class="de1">&nbsp;</div></li><li class="li2"><div class="de2">YUI<span class="br0">&#40;</span><span class="br0">&#41;</span>.<span class="kw2">use</span><span class="br0">&#40;</span><span class="st0">'scrollview'</span><span class="sy0">,</span> <span class="kw2">function</span><span class="br0">&#40;</span>Y<span class="br0">&#41;</span> <span class="br0">&#123;</span></div></li><li class="li1"><div class="de1">    ...</div></li><li class="li1"><div class="de1"><span class="br0">&#125;</span><span class="br0">&#41;</span><span class="sy0">;</span></div></li><li class="li1"><div class="de1">&nbsp;</div></li></ol></pre></div><div class="nonumbers"><pre class="javascript" style="font-family:monospace;">&nbsp;

YUI().use('scrollview', function(Y) {
    ...
});
</textarea></div>
<p>The <code>scrollview</code> module pulls in the basic ScrollView and also the ScrollViewScrollbars plugin. It has code which plugs the scrollbar plugin into the ScrollView base class:</p>

<h3>Instantiating The ScrollView Widget</h3>

<p>As with the <a href="scrollview-base.html">Base ScrollView</a> example, we provide the markup for the ScrollView content on the page, as shown below:</p>

<div id="syntax-95ab05b8cb08d374b3c7329d005601be" class="yui-syntax-highlight"><div class="numbers"><pre class="javascript" style="font-family:monospace;"><ol><li class="li1"><div class="de1"><span class="sy0">&lt;</span>div id<span class="sy0">=</span><span class="st0">&quot;scrollview-content&quot;</span> <span class="kw2">class</span><span class="sy0">=</span><span class="st0">&quot;yui3-scrollview-loading&quot;</span><span class="sy0">&gt;</span></div></li><li class="li1"><div class="de1">    <span class="sy0">&lt;</span>ul<span class="sy0">&gt;</span></div></li><li class="li1"><div class="de1">        <span class="sy0">&lt;</span>li<span class="sy0">&gt;</span>AC<span class="sy0">/</span>DC<span class="sy0">&lt;/</span>li<span class="sy0">&gt;</span></div></li><li class="li1"><div class="de1">        <span class="sy0">&lt;</span>li<span class="sy0">&gt;</span>Aerosmith<span class="sy0">&lt;/</span>li<span class="sy0">&gt;</span></div></li><li class="li2"><div class="de2">        <span class="sy0">&lt;</span>li<span class="sy0">&gt;</span>Billy Joel<span class="sy0">&lt;/</span>li<span class="sy0">&gt;</span></div></li><li class="li1"><div class="de1">        <span class="sy0">&lt;</span>li<span class="sy0">&gt;</span>Bob Dylan<span class="sy0">&lt;/</span>li<span class="sy0">&gt;</span></div></li><li class="li1"><div class="de1">        ...</div></li><li class="li1"><div class="de1">    <span class="sy0">&lt;/</span>ul<span class="sy0">&gt;</span></div></li><li class="li1"><div class="de1"><span class="sy0">&lt;/</span>div<span class="sy0">&gt;</span></div></li></ol></pre></div><div class="nonumbers"><pre class="javascript" style="font-family:monospace;"><span class="sy0">&lt;</span>div id<span class="sy0">=</span><span class="st0">&quot;scrollview-content&quot;</span> <span class="kw2">class</span><span class="sy0">=</span><span class="st0">&quot;yui3-scrollview-loading&quot;</span><span class="sy0">&gt;</span>

        ...
    </ul>
</div></textarea></div>
<p>And we instantiate the ScrollView instance in the same way, providing the <code>srcNode</code> attribute during construction, so it uses the markup above for it's content:</p>

<div id="syntax-6393ac06f784e14d1e3ff1b299a57a4f" class="yui-syntax-highlight"><div class="numbers"><pre class="javascript" style="font-family:monospace;"><ol><li class="li1"><div class="de1">YUI<span class="br0">&#40;</span><span class="br0">&#41;</span>.<span class="kw2">use</span><span class="br0">&#40;</span><span class="st0">'scrollview'</span><span class="sy0">,</span> <span class="kw2">function</span><span class="br0">&#40;</span>Y<span class="br0">&#41;</span> <span class="br0">&#123;</span></div></li><li class="li1"><div class="de1">&nbsp;</div></li><li class="li1"><div class="de1">    <span class="kw2">var</span> scrollView <span class="sy0">=</span> <span class="kw2">new</span> Y.<span class="me1">ScrollView</span><span class="br0">&#40;</span><span class="br0">&#123;</span></div></li><li class="li1"><div class="de1">        id<span class="sy0">:</span> <span class="st0">&quot;scrollview&quot;</span><span class="sy0">,</span></div></li><li class="li2"><div class="de2">        srcNode<span class="sy0">:</span> <span class="st0">'#scrollview-content'</span><span class="sy0">,</span></div></li><li class="li1"><div class="de1">        height<span class="sy0">:</span> <span class="nu0">310</span><span class="sy0">,</span></div></li><li class="li1"><div class="de1">        flick<span class="sy0">:</span> <span class="br0">&#123;</span></div></li><li class="li1"><div class="de1">            minDistance<span class="sy0">:</span><span class="nu0">10</span><span class="sy0">,</span></div></li><li class="li1"><div class="de1">            minVelocity<span class="sy0">:</span><span class="nu0">0.3</span><span class="sy0">,</span></div></li><li class="li2"><div class="de2">            axis<span class="sy0">:</span> <span class="st0">&quot;y&quot;</span></div></li><li class="li1"><div class="de1">        <span class="br0">&#125;</span></div></li><li class="li1"><div class="de1">    <span class="br0">&#125;</span><span class="br0">&#41;</span><span class="sy0">;</span></div></li><li class="li1"><div class="de1">&nbsp;</div></li><li class="li1"><div class="de1">    scrollView.<span class="me1">render</span><span class="br0">&#40;</span><span class="br0">&#41;</span><span class="sy0">;</span></div></li><li class="li2"><div class="de2"><span class="br0">&#125;</span><span class="br0">&#41;</span><span class="sy0">;</span></div></li></ol></pre></div><div class="nonumbers"><pre class="javascript" style="font-family:monospace;">YUI<span class="br0">&#40;</span><span class="br0">&#41;</span>.<span class="kw2">use</span><span class="br0">&#40;</span><span class="st0">'scrollview'</span><span class="sy0">,</span> <span class="kw2">function</span><span class="br0">&#40;</span>Y<span class="br0">&#41;</span> <span class="br0">&#123;</span>

    var scrollView = new Y.ScrollView({
        id: "scrollview",
        srcNode: '#scrollview-content',
        height: 310,
        flick: {
            minDistance:10,
            minVelocity:0.3,
            axis: "y"
        }
    });

    scrollView.render();
});</textarea></div>
<p>Again, for this example, since we want a vertically scrolling ScrollView widget, we also give it a height during construction and constrain flicks to the "y" axis.</p>

<p>As the last step, to see the functional ScrollView on the page, we call <code>scrollView.render()</code>.</p>

<p>The only difference, compared to the <a href="scrollview-base.html">Base ScrollView</a> example, is that the ScrollViewScrollbars plugin has been pulled down and plugged in by the <code>scrollview</code> module code shown above, so the ScrollView now has a scroll indicator. The scroll indicator is styled with rounded corners in browsers which support CSS rounded corners natively.</p>

<h3>Accessing The Scrollbars Plugin API</h3>

<p>As discussed in the <a href="http://developer.yahoo.com/yui/3/scrollview/index.html#scrollbars">ScrollBar Plugin</a> documentation, the API to control scrollbars is available on the scrollview instance, through the <code>scrollView.scrollbars</code> property. The ScrollBar plugin doesn't have too complex of an api, just a few methods to hide and show the scrollbars:</p>

<div id="syntax-5fded303812dc52c213dc4cbb2c89633" class="yui-syntax-highlight"><div class="numbers"><pre class="javascript" style="font-family:monospace;"><ol><li class="li1"><div class="de1">    <span class="coMULTI">/* </span></div></li><li class="li1"><div class="de1"><span class="coMULTI">&nbsp;     scrollView.scrollbars is an instance of the ScrollViewScrollbars plugin </span></div></li><li class="li1"><div class="de1"><span class="coMULTI">&nbsp;   */</span></div></li><li class="li1"><div class="de1">    scrollView.<span class="me1">scrollbars</span>.<span class="me1">hide</span><span class="br0">&#40;</span><span class="br0">&#41;</span><span class="sy0">;</span></div></li><li class="li2"><div class="de2">    scrollView.<span class="me1">scrollbars</span>.<span class="me1">show</span><span class="br0">&#40;</span><span class="br0">&#41;</span><span class="sy0">;</span> </div></li><li class="li1"><div class="de1">    scrollView.<span class="me1">scrollbars</span>.<span class="me1">flash</span><span class="br0">&#40;</span><span class="br0">&#41;</span><span class="sy0">;</span></div></li><li class="li1"><div class="de1"><span class="br0">&#125;</span><span class="br0">&#41;</span><span class="sy0">;</span></div></li></ol></pre></div><div class="nonumbers"><pre class="javascript" style="font-family:monospace;">    <span class="coMULTI">/*

    scrollView.scrollbars.hide();
    scrollView.scrollbars.show(); 
    scrollView.scrollbars.flash();
});</textarea></div>
<h3>Suppressing Default Link Behavior</h3>

<p>In this example, the scrolling surface is populated with links. To prevent links' default action (page navigation) from taking place after a scroll, we look at the <code>lastScrolledAmt</code> property of our ScrollView instance; on a simple click, that number will be very close to zero, whereas after scroll that number will be much higher.  In this case, we're using a 2px threshold.</p>
